[0053] Specifically, the structure and connection relationship of the fluid replenishing mechanism 8 will be further described.

[0054] The working principle of the utility model is as follows: the flue gas enters the desulfurization tower 1 through the cooperation of the flue gas rack 31, the flue gas pipe 32 and the smoke inlet fan 33; the dilute sulfuric acid solution is circulated and transported in the desulfurization tower 1 through the cooperation of the collecting tank 41, the circulating spray rack 42, the circulating pipe 43 and the second pump body 44; the hydrogen peroxide is sprayed in the desulfurization tower 1 through the cooperation of the hydrogen peroxide spray rack 21, the hydrogen peroxide tank 22, the first pump body 23 and the first liquid infusion pipeline 24, and is mixed with the dilute sulfuric acid solution to form a dilute sulfuric acid solution containing a certain concentration of hydrogen peroxide.

[0055] The sulfur dioxide in the flue gas contacts the dilute sulfuric acid solution containing a certain concentration of hydrogen peroxide sprayed from the top in the desulfurization tower 1 in countercurrent and reacts. The sulfur dioxide is oxidized and absorbed by the hydrogen peroxide to become dilute sulfuric acid, and falls into the collecting tank 41 to achieve circulating transportation. After the desulfurized flue gas is removed of acid mist and nitrogen oxides by the electric precipitator 51 at the top of the desulfurization tower 1, it is transported to the inside of the 120m high chimney 7 through the exhaust pipe 52 and the exhaust fan 53, and discharged from the chimney 7.

[0056] When the liquid level sensor 64 inside the collecting tank 41 detects that the liquid level inside the collecting tank 41 reaches the set value, the collection pipe 45 and the external pump body cooperate to transport about 25% of the dilute sulfuric acid produced after the desulfurization reaction to the outside of the collecting main pipe, and then transported by the external collecting main pipe to the final absorption acid circulation tank (not shown in the figure) of the acid production system as water for acid concentration adjustment.

[0057] When the sulfur dioxide sensor 62 on the inner wall of the desulfurization tower 1 detects an increase in sulfur dioxide in the flue gas, the controller 61 controls the frequency converter 67 to operate, and the frequency converter 67 operates to adjust the motor speed in the first pump body 23, thereby increasing the output of hydrogen peroxide to allow sulfur dioxide to fully react with hydrogen peroxide.

[0058] When the concentration sensor 63 detects that the concentration of hydrogen peroxide in the dilute sulfuric acid solution containing a certain concentration of hydrogen peroxide in the collecting tank 41 is low, the controller 61 controls the operation of the liquid replenishing mechanism 8, and quantitatively adds hydrogen peroxide to the collecting tank 41 through the cooperation of the third pump body 81 and the liquid replenishing pipeline 82 to make the proportion balanced and improve the treatment effect.

[0059] In order to achieve quantitative delivery, flow detectors 65 are provided on the first infusion pipeline 24 , the circulation pipe 43 and the infusion pipeline 82 .

[0060] It should be noted that the desulfurization efficiency can also be adjusted by changing the motor speeds of the smoke inlet fan 33 and the smoke exhaust fan 53 through the controller 61.

[0061] In summary, the utility model embodiment is a device for increasing the desulfurization efficiency by using hydrogen peroxide. The device uses hydrogen peroxide (hydrogen peroxide) solution as an absorbent, adopts a high-efficiency filler desulfurization tower, and utilizes the advantage of the large specific surface area of ​​the filler to improve the desulfurization efficiency. The desulfurization tower 1 and the circulation tank assembly 4 and the electrostatic precipitator 51 are designed as an integral glass fiber reinforced plastic structure. The electrostatic precipitator 51 is placed on the top of the desulfurization tower 1. A new type of tower, tank, and device integrated device is developed. It has strong adaptability to flue gas and can simultaneously remove pollutants such as sulfur dioxide and acid mist in the flue gas, and has the advantages of low investment, small footprint, high removal rate, simple operation and maintenance, and low operating costs.
